Hi,
just out of curiosity: How did you come running a `2.0.0-M1`? As far as we know, this was never released. Did you build it on your own or did you get it elsewhere?
Because this version is nearly 8 years old, we cannot say for sure, what the file layout looks like. If you have a testing environment (or can create one), the best way would be to start a 1.60 with the scm folder. This is the prerequisite for an automated update to 2.x.
We would love to hear, whether this works.
